3 Claims. (CI. 58-16) My invention relates to alarm clocks and has for its object the production of an alarm clock having an indicating means that is visible in the dark as well as in the daylight such that the user can by merely looking at the dial be assured that the alarm mechanism is always in its operative position so that the alarm will sound when the time movement permits the alarm mechanism to operate.

Its further object is to produce a device that will display an indicator having mounted thereon some means that will make the indicator definitely visible in the dark so that the sleeper can be advised when he looks at the clock dial, if the illuminated or luminous indicator is visible, that the alarm mechanism is set to sound the alarm at the time for which the alarm is set.

It is well known that alarm clocks generally have a manual means for shutting off the alarm as soon as the sleeper is awakened. In fact, he must usually arise to shut off the alarm in order not to disturb other sleepers in the vicinity, so that the next evening the user may forget to reset this shut off mechanism and in case the user should forget to reset the alarm mechanism to its operative position, the indicator not being visible, will immediately direct the attention of the user to the fact that he must reset the operative mechanism to permit the alarm to sound.

I accomplish these objects by the means shown in the accompanying drawing in which:

Fig. 1 shows a partial front view of a clock with the indicator in its luminous or illuminated indicating position behind the aperture in the dial.

Fig. 2 is a side View of Fig. 1.

Fig. 3 is a top View of Fig. 1.

Fig. 4 is a front view similar to that shown in Fig. 1 but in which the indicator is in its black indicating position.

Fig. 5 is a side view of Fig. 4.

Fig. 6 is a top view of Fig. 4.

Similar numerals represent the same parts throughout the several views.

In the drawing I and 2 represent the front and rear plates of the usual alarm clock movement which are fastened together by means of the usual pillars 3, shown. Mounted between said plates I and 2 is the usual time movement train, indicated at 20 in Fig. 4, with its usual trip cam mechanism for releasing the alarm train whose spring driven gears (indicated at ZI in Fig. 4) gear into and operate the speed regulating vane or fly 4 shown. Associated with the fly 4 is a projection 6 on a stop lever 5 which is fastened to a bushing 'I mounted on a shaft 8 which is slidably mounted in plates I and 2 and has a button 9 for manually operating same. Integral with 5 is a resilient member II) which has an angular positioning means I I which engages either side of the edge of plate I and retains the shaft 8 and the projection 6 out of engagement with the fly 4 as shown in Figure .3 permitting it to rotate or be in engagement with said fly 4 as is shown in Figure 6 holding it against rotation. Resilient member II] has a notch or cam surface I2 cut in its side as shown 10 in Figures 3 and 6 into which passes a projection I3 from the arm I4 which is mounted on a shaft I5 which is journalled in plates I and 2. Arm I4 has a plate I6 which preferably carries a luminous material I! the balance of the surface of I6 being 15 black or colored around said luminous material and said arm I4 is so shaped that its center of gravity tends to keep the plate I6 (when free to move) to move to the left or in a clockwise direction so that projection I3 will always rest against the resilient member I0 and thus position the plate I6 with its luminous material directly in line with the aperture I8 in the dial, as shown in Figure 1, when the projection I3 is resting in the bottom of the notch I2 in said member I 0 as 25 shown in Figure 3. It is evident that the luminous part I! is then visible through the aperture I8 in which position the alarm will be in position to sound as the fly 4 is free from the projection 6 in said position as is shown in Figure 3. 30

When the projection I3 is resting against resilient member III away from the notch I2, as shown in Figure 6 and Figure 4, it is evident, that the luminous part I! of plate IE on arm I4 is held away from said aperture I8 of the clock dial I9 35 so that only the black or other colored portion is visible through said aperture. An inspection of Figure 6 also shows that the projection I3 is holding the fly 4 against rotation so that in this position the alarm cannot be sounded. The user ob- 40 serving this condition of the indicator must pull out the manual means or button 9 to the position shown in Figure 3 where he will be assured of the sounding of the alarm at the time he wants it to do so.

In order to make the luminous part of the indicator more conspicuous in daylight I associate some coloring means with the luminous means and in the preferred form of my invention in using it with ordinary alarm clocks I prefer to use 50 luminous paint which can be colored to suit the daylight requirement.

While I have here shown one form of my invention using luminous material or paint on the indicator I do not wish to limit my invention to 65 the use of same but where electricity is available to operate clocks having alarm sounding means, it is evident, that I can use an electric light behind the aperture that will show through or use therewith a translucent colored screen or the like, as an indicating means, without departing from the spirit of my invention.

I claim:

1. In an alarm clock, a time mechanism, an alarm mechanism including a frame, means on said time mechanism to release said alarm mechanism at a predetermined time, a dial having an aperture, a lever pivotally mounted in said frame,

a movably mounted indicating means on said lever and adjacent to said aperture,,manua1lyoperated means comprising a shaft slidahly mounted in said frame, a resilient positioning member mounted on said shaft, and an arm on said member co-acting to control the operation of said alarm mechanism, said member having a cam co-acting with said lever to position said indicating means to register with said aperture.

2. In an alarm clock, a time mechanism, an alarm mechanism including a frame, means on said time mechanism to release said alarm mechanism at a predetermined time, a dial having an aperture, a lever pivotally mounted on said frame,

a movably mounted indicating means on said lever and adjacent to said aperture, manually operated means comprising a shaft slidably mounted in said frame, a resilient positioning member mounted on said shaft and co-acting with said frame, and an arm on said member co-acting to control the operation of said alarm mechanism, said member having a camv co.-acting with said lever to position said indicating. means to register with said aperture.

3. In an alarm clock, a time mechanism, an alarm mechanism including a frame, means on said time mechanism to release said alarm mechanism at a predetermined time, a dial having an aperture, a lever pivotally mounted on said frame, a movably mounted luminous indicating means on said lever and adjacent to said aperture, manually operated means comprising a shaft slidably mounted in said frame, a resilient positioning member mounted on said shaft and co-acting with. said. frame, and an arm on said member co-acting to control the operation of said alarm mechanism, said member having a cam co-acting with said lever to position said indicating means. to register with said aperture.
